Abstract

A holographic display system for attaching to a firearm provides a user with enhanced target acquisition information, such as real time ballistic solutions, fused thermal imaging, extended zoom, and automatic target recognition. The holographic display system may include a waveguide, a light engine, holographic optical element, a casing and a coupler. The holographic optical element is positioned between the light engine and the waveguide and the coupler is attached to the casing, The light engine is configured to generate and transmit displayable information to the holographic optical element, and the holographic optical element includes a diffractive grating configured to guide the displayable information into the waveguide. The waveguide is configured to propagate the displayable information and transmit the displayable information as a distant image to a user of the holographic display system.

Claims (10)

1 . A holographic display system for attaching to a firearm, the holographic display system comprising:

a casing including an enclosure and a receptacle;

a light engine housed in the enclosure;

a waveguide encompassed by the receptacle;

a first holographic optical element at a first end of the waveguide and positioned between the light engine and the waveguide;

a second holographic optical element at a second end of the waveguide; and

a coupler attached to the casing, the coupler sized and configured to mount to the firearm, wherein the light engine is configured to generate and transmit displayable information to the first holographic optical element, wherein the first holographic optical element is positioned and configured to guide the displayable information into the waveguide, and wherein the waveguide is configured to propagate the displayable information and transmit, via the second holographic optical element, the displayable information as an image to a user of the holographic display system; and

a front objective and a rear ocular exit, wherein the waveguide is positioned between the front objective and the rear ocular exit such that the displayable information exits the waveguide in a second focal plane of the holographic display system.

2 . The holographic display system according to claim 1 , wherein the image includes a thermal characterization.

3 . The holographic display system according to claim 1 , wherein the first holographic optical element includes a first diffractive grating.
